android - recorridos - Usar gps para obtener la distancia que una persona ha caminado

app para medir distancia recorrida en bicicleta

Question

chicos, puedo obtener la longitud de ubicación actual y Latitude usando el siguiente código. Tengo dos botones Start walking and Stop Walking.

Al hacer clic en Start Walking obtendrá la ubicación actual (longitud y latitud) la persona comenzará a caminar desde la posición A (fuente) y caminará desde algún momento y regresará a A (ahora se convierte en destino), luego hará clic en detener caminando botón.

Ahora necesito mostrarle al usuario estos detalles:

1.Distancia de que él caminó en Kms.

2. Tiempo que tomó en minutos.

(opcional) 3.velocidad o velocidad promedio.

Cómo lograr esto

Answer 1

Ante todo. Esto es más que una pregunta sobre un problema y luego recibirá una respuesta. Las personas en este foro no te harán trabajar para ti.

Ahora a una manera de lograr lo que quieres.

Debe usar un servicio para realizar un seguimiento del usuario y las ubicaciones. La manera más fácil sería incorporar el servicio mytracks que está disponible como complemento de su aplicación o usar código de mytracks para crear su propio servicio de seguimiento. http://code.google.com/p/mytracks/

función para calcular la distancia ...

public double getDistance(double lat1, double lon1, double lat2, double lon2) {
    double latA = Math.toRadians(lat1);
    double lonA = Math.toRadians(lon1);
    double latB = Math.toRadians(lat2);
    double lonB = Math.toRadians(lon2);
    double cosAng = (Math.cos(latA) * Math.cos(latB) * Math.cos(lonB-lonA)) +
                    (Math.sin(latA) * Math.sin(latB));
    double ang = Math.acos(cosAng);
    double dist = ang *6371;
    return dist;
}

}

Answer 3

Puede calcular la distancia entre dos ubicaciones geográficas con la función distanceTo ()
Location destination =new Location("gps");
destination.setLatitude(lat);
destination.setLongitude(lng);
float dist=user_location.distanceTo(destination);
